Second, but on a more positive note, digging a tunnel that's X times longer than the Channel Tunnel doesn't have to take X times as long as digging the Channel Tunnel. New York to Los Angeles is under land except for a few river crossings, so there is no reason why you couldn't be digging at multiple places at once and create multiple sections of the tunnel concurrently. That would be more expensive, and getting the segments to line up exactly won't be easy, but should be doable.
